1. The admitting diagnosis was revision of hip arthroplasty. The patient had undergone a total left hip arthroplasty five weeks earlier for osteoarthritis. The prosthesis worked well until the previous week, when she heard a pop. X-rays taken on admission showed a superior displacement of the left acetabular cup, which continues to migrate proximally despite bed rest. The left acetabular component of the prosthesis was moved back to the correct location and re-cemented in place. Three days after surgery, the patient had a hemoglobin of 10.9 and was transfused with two units of packed red blood cells. Hemoglobin count improved, and the patient was discharged on the fifth postoperative day. (2 PCS codes)
2. The patient was admitted for repair of spinal stenosis. An excision of discs at C3-C4 and C5-C6 with fusion was carried out using an anterior approach. A graft of bone was excised from the right iliac crest. (3 PCS codes)

He was taken to the operating room, where a hemigastrectomy with Billroth I anastomosis of the duodenum was performed. (3 PCS codes)
